SPACING MECHANISM FOR LACING-HOOK-SETTING MACHINES.

Specification of Letters Patent.

Patented July 13, 1909.

To all whom it may concern:

Be it known that I, l/VARREN F. Fnasnn, a subject of King Edward VII, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Spacing Mechanism for Lacing-l-look-Setting Machines, of which the following is a specification.

This invention relates to machines for setting lacing hooks in the up iers of boots and shoes and is of that particular class of lacing hook setting machines known as automatic lacing hook setting machincs that is, in which the lacing hooks are fed to a setting mechanism, which sets the lacing hooks in the upper of the boot or shoe, and said upper is fed automatically the desired distance to properly space the lacing hooks which are set therein.

The object of this invention is to provide a lacing hook setting machine of the class hereinbe'fore set forth in which the upper is placed in a holder therefor and the holder is automatically operated to move intermittently in one direction while the lacing hooks are set in said upper by the setting mechanism. At the end of the movement of the holder in said direction, the lacing hook feed ing mechanism and mechanism for feeding the holder, with the upper held thereon, are thrown out of action automatically and the machine stops, whereupon the operator opens the clanming members of the holder, removes the left hand upper therefrom, in scrts a right hand upper in the clamp and starts the machine, which. thereupon feeds lacing hooks, sets them in the upper and feeds the upper intermittently until a series of lacing hooks have been set therein, whereupon the lacing hook feeding mechanism, the setting mechanism, and the mechanism for intermittently moving the upper relatively to the setting mechanism are thrown out of action and the machine is automatically stopped again. The operator then removes the right hand upper and inserts a left hand upper, thus alternately setting lacing hooks in the right and left hand uppers of the boots and without loss of time.

in the machine of this invention instrumentalities are provided to adjust the mechanism by which the holder for the upper and the upper held thereon are intermittently fed, so that the distance between the lacing hooks may be increased or diminished, as desired. The mechanism is also so constructed that after a series of lacing hooks have been. set in the upper, a single lacing hook may be set by the operator in the upper in any desired position, so that if a lacing hook is poorly set or if a lacing hook is damaged. in any way, the same may be removed from the upper after the series of lacing hooks have been set therein and a new lacing hook set to take the place of the damaged one, the machine being so constructed that the operator can, at will, throw the mechanism for feeding the upper out of action, thus leaving the lacing hook setting and the lacing hook feeding mechanisms in action, in order that a single lacing hook may be set in the upper, as hereinbcforc described.

One of the chief advantages derived from an automatic lacing hook setting machine, constructed as hercinbeforc set forth, is that by setting lacing hooks in the upper in one direction and then setting lacing hooks in an upper in the opposite direction no time is lost by the mechanism which feeds the upper upon its return movement, as a series of lacing hooks are set while the upper feeding mechanism is moving in one direction and while said upper feeding mechanism is moving in the opposite direction.

The invention consists in the combination and arrangement of parts set forth in the following specification and particulanypointed out in the claims thereof.

The drawings pm'ticularly illustrate the holder for the upper and the mechanism by which the intermittent movement given to said upper in one direction and then thrown out of action, subsequr'aitly returning to its starting point in a series of intermittent movements and feeding an upper in the opposite direction and then again being thrown out of action.

The lacing hook feeding and setting mechanisms are only slightly indicated in the drawings, they being well known to those skilled in the art and involving no new or patentable matter, in themselves.

Referring now to the drawings: Figure l is a plan view of a portion of my improvedv lacing hook setting machine, the same being broken away and partly shown in section for the sake of clearness in. illustration. Fig. 2 is a sectional elevation. taken on line 22 of Fig. 1. Fig. 3 is a sectional plan taken on line 33 of Fig. 2. Fig. i is a sectional plan taken on line 44 of Fig. 2, illustrating a right hand upper in position to have a lacing hook set therein in full lines and a left hand upper in dotted lines. Fig. 5 is a sectional e evation taken on line 55 of Fig. 4. Fig. 6 is a sectional elevation taken on line 66 of Fig. 1, illustrating the clutch mechanism. Fig. 7 is a sectional elevation taken on line 77 of Fig. 1. Fig. 8 is a sectional plan taken on line 88 of Fig. 2. Fig. 9 is a sectional elevation taken on line 99 of Fig. 2. Fig. 10 is a left hand side elevation of the mechanism for throwing out of action the mechanism which imparts an intermittent feeding movement to the holder and the upper held thereon. Fig. 11 is a sectional elevation taken on line 1111 of Fig. 10. Fig. 12 is a front elevation of the holder for the upper, the gages for said upper which determine the position of the same in the machine, when the upper is first laced therein, together with a portion of the lacing hook carrier and the anvil against which the lacing hook is set. Fig. 13 is a development of the cam by which an intermittent movement is imparted to the holder for the upper and the upper held thereon. In Fig. 4 the lacing hooks are dotted in the position they will assume when driven in the upper.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 15 is the frame of the machine; 16 is the main driving shaft journaled to rotate in suitable bearings in said frame and by means of which the mechanisms for setting the lacing hook, for feeding the lacing hook, and for feeding the holder for the upper are actuated.

17 is a portion of the lacing hook carrier to which a vertical and horizontal movement are imparted to set the lacing hook and to release the carrier from the same, respectively, by mechanism not shown in the drawings, but well known to those skilled in this art. The raceway 18 (Fig. 2) is indicated in dotted. lines, the same leading from a suitable hopper in which the lacing hooks are placed and separated to pass down said raceway, and from said raceway to be fed to the lacing hook carrier 17 by suitable mechanism not shown in the drawings, but well known to those skilled in this art.

19 is the holder for the upper of the boot or shoe in which the lacing hooks are to be set.

Refering to Figs. 1, 2, 3, 4, 5 and 12, it will be understood that this holder consists of a rocker-frame 21 which is fastened to a vertical rock-sh aft 22 journaled to rock in a bearing 23 in the frame of the machine and consisting of a hub 24 with three arms 25, 26, and 27 thereon (Fig. 3). The arm 27 has a segmental gear 28 thereon. The arms and 26 each has a sleeve 29 clamped thereto and in each of said sleeves is a plunger 30 adapted to slide therein and pressed downwardly by means of a spring 31. Said plungers have arms 32, 32 fast thereto and to these arms is fastened the upper or movable clamp plate 33. A relatively stationary clamp plate 34 is supported by brackets 35 which eXtend downwardly from brackets 36 fast to the sleeves 29 so that normally the clamp-plate 33 is pressed downwardly by the spring 31 to clamp the upper 20 between the clampplates 33 and 34.

The plungers 30 have clamped to their upper ends collars 37, 37 and these collars bear against the upper face of a segmental plate 38. The segmental plate 38 has two studs 39 and 40 fast thereto extending upwardly therefrom and adapted to slide in bearings formed in the arms 41 and 42, respectively, said arms extending outwardly from the upper portion 15 of the frame. A vertical reciprocatory motion is imparted to the studs 39 and 40 and to the segmental plate 38 fast thereto by means of a lever 43, pivoted at 44 to the frame and connected by a rod 45 to a suitable treadle. The lever 43 is operatively connected to the stud 40 by a screw 46 and block 47, which block is clamped to the stud 40. It will thus be seen that by depressing the treadle connected to the lever 43, said lever will be rocked upon its pivot and will raise the studs 39 and 40 and the plate 38 fast thereto, thus raising the collars 37, 37 and elevating the plungers 30, 30 to which they are attached, thus moving the clamp plate 33 upwardly, away from the stationary clamp-plate 34, and allowing the upper 20 to be inserted or removed from between the clamp-plates.

An intermittent reciprocatory motion is imparted to the holder 19 and to the up er 20 held thereon by the mechanism which I will now proceed to describe. The main driving shaft 16 has fastened thereto, at the left hand side of the machine, a pinion 43 (Fig. 10) which meshes into an intermediate gear 49, said. intermediate gear meshing into a gear 50 loosely mounted upon the shaft 51. A clutch block 52 is fastened to the shaft 51, outside and adjacent to the gear 50. This clutch block has a locking lever 53 pivoted thereto at 54. A spiral spring 55 is located within the recess formed in the end of the shaft 51 and bears against one end of the locking lever 53, thus forcing the free end of said locking lever into any one of the radial slots 56 formed in the adjacent face of the gear 50. This lever 53 and the clutch block 54 thus lock the gear 50 to the shaft 51 when the parts are in the position illustrated in Fig. 11.

When it is desired to disconnect the gear 50 from the shaft 51, so that it will rotate freely thereon without rotating the shaft, the operator depresses the treadle (not shown in the drawings) to which is connected a treadle rod 57, the upper end of said treadle rod being connected to a rocker arm 58 fast to a rock-shaft 59 having an arm 60 fast thereto, with its free end adapted to engage the upper end of the locking lever 53, (Fig. 11.). As shown in the drawings, the arm 60 is out of engagement with the locking lever 53, but when the operator rocks said arm 60 toward the left (Fig. 11) by means of the treadle, through the treadle rod 57 and rock-shaft 59 the locking lever 53 will be rocked upon its pivot 54 to disengage the lower end (Fig.11) of said locking lever from the gear 50 and allow said gear to rotate freely, whereupon the shaft 51 will remain stationary, while the driving shaft will continue its rotations without in any way operating the shaft 51, which shaft, as will now be described, operates the intermittent feeding mechanism for the holder for the upper of the boot.

The shaft 51 has a cam 61 fast thereto, said cam having a path 62 cut in its periphery, which consists of a series of rests 63, 63 and throws 64, 64. A cam roll 65 projects into said cam path 62 (Fig. 2) and is journaled to rotate upon a stud 66 fast to an arm 67, which, in turn, is fastened to a vertical rock-shaft 68, the upper end of which has fastened thereto a lever 69, which is operatively connected to a lever 70 by a stud 71v fast to a slide 72 and projecting upwardly therefrom into a sliding block 73 arranged to slide in a slot 74 formed in the lever 69. The slide 72 is adjustable longitudinally of a slot 75 formed in the lever 70 and is adjusted in said slot by means of a screw 76 having screw-threaded engagement with said slide and rotatably mounted upon the lever 70. At its inner end said screw is connected by a suitable joint 77 to a rotary shaft 78, said rotary shaft having a knob or handle 79 fast thereto, by means of which it may be conveniently rotated. A worm 80 is formed upon the periphery of the shaft 7 8 and meshes into a worm gear 81 fast to a vertical shaft 82, to the upper end of which is fastened a disk 83, which is graduated by lines upon the periphery thereof which are indicated by means of an index finger 84 fast to the frame of the machine, with its free end bearing against the periphery of the grad uated disk 83. The lever 70 is fast to a stud 85 journaled to rock in a bearing 86 upon the upper portion 15 of the machine, and said lever has a segment gear 87 formed upon one end thereof and meshing into the seg ment gear 28. Thus it will be seen that when the shaft 51 is rotated by means of the gearing hereinbefore described and illustrated in Figs. 10 and 11, the cam 61 will be rotated, and because of the rests and throws in the path 62 thereof, an intermittent rocking movement will be imparted to the arm 67, rock-shaft 68, lever 69 and lever 70, which rocking movement will be imparted by the lever 70, through the segmental gears 87 and 28, to the holder 19 and upper which is held by the clamp plates 33 and 34 upon said holder. The shaft 51 has a cam 88 fast thereto and against the periphery of said cam a roll 89 bears, said roll being rotatably mounted upon a lever 90, the end of said lever opposite to that to which the roll is attached being adapted to engage a locking arm 91 pivoted at 92 in the slot 93 formed in the enlarged end 94 of the main driving shaft 16, (see Figs. 1 and 7). When the locking arm 91, is freed by the lever mov ing downwardly the spring 95 forces said locking arm forward until the tooth 96 thereon drops into a recess 97 formed in the enlarged end 98 of the pulley shaft 99, to which the driving pulley 100 is fastened. When this happens, the pulley 100, by means of the shaft 99 and the locking arm 91, causes the shaft 16 to be rotated until such time as the lever 90 is moved by the spring 101 into the recess 102 in the periphery of the cam 88 and thus moves the free end of said lever up wardly to engage the locking arm 91. The lever 90 may also be rocked independently of the cam 88, when the parts are in the po sition illustrated in Fig. 6, by means of a treadle rod 103 which leads to a treadle (not shown in the drawings) conveniently set to be operated by the operator of the machine when it is desired to rotate the main driving shaft of the machine independently of the automatic mechanism illustrated in Fig. 6. To assist the operator in placing the upper in the machine correctly to set the lacing hool s therein, two front edge gages 104, 104 are supplied which are fastened to the upper clamp-plate 33, and furthertwo top edge gages 105, and 106 are supplied, each of which is pivoted, respectively, to a screw 107 fast to a collar 108, which collar is clamped to the anvil 14. These top edge gages and 106 can be adjusted laterally thereof and then locked in position by means of screws 109, 109 which project through slots 110, 110.

The general operation of the machine hereinhefore specifically and to some extent, in general, described is as follows: Assuming that the operator desires to set lacing hooks in a right hand upper, he rai. the clampplate 33, as hereinbefore described, inserts the upper 20 between said clamp plates 33 and 34, with the upper edge of the upper bent slightly upward to engage the top gage 106 and with the front edge of the upper, bearing against the front edge gages 104, 104. He then releases the clamping treadle which allows the plate to descend and clamp the upper between itself and the clamp plate 34. The operator then depresses the treadle which is connected to the rod 103 (Fig. 6), thus rocking the lever 90, releasing the looking arm 91, which is immediately forced by the spring 95 into the recess 97, thus locking & 927,647
